My son worked for Goodlife and needed his cell phone for client contacts, where do i claim this?

If you have the installed Home and Business, you can click on the forms icon, top menu and then type in T777.  In order to make this claim, he must have a form T2200 signed by his employer stating that the cellphone was a condition of employment.  The employer will provide the form, fill it in and sign it.  You can only deduct what is allowed per the form.
